Chapter 43. System.Timers

The System.Timers namespace provides
the Timer class, which periodically raises an
Elapsed event. It is a server-based component
designed to be used in a multithreaded environment and is thus more
accurate than many other Windows-based timers. Unlike
System.Windows.Forms.Timer, a server-based timer
is not dependent on a user interface message pump. Figure 43-1 shows the class diagram for this namespace.
